512-bit Vector DSP IP, Dual Core with Functional Safety

Overview

The ASIL B and C compliant ARC® VPXxFS DSP IP is a family of VLIW/SIMD processors enabling automotive system-on-chip (SoC) designers to accelerate advanced driver assistance systems (ADAS), RADAR and LiDAR sensor processing application development and ISO26262 certification for systems using digital signal processing.

The VPXxFS Family supports multiple vector lengths and core configurations:

128-bit vector word – VPX2FS (single core), VPX2FSx2 (dual core)

256-bit vector word – VPX3FS (single core), VPX3FSx2 (dual core)

12-bit vector word – VPX5FS (single core), VPX5FSx2 (dual core), VPX5FSx4 (quad core)

The VPXxFS Family comes with integrated hardware safety features such as ECC protection for memories and interfaces, safety monitors and lockstep mechanisms that achieve the most stringent levels of ISO 26262 functional safety compliance.

To speed application software development, the VPXxFS Family is supported by the vendor’s ARC MetaWare tools, which provide a comprehensive and vector-length agnostic software programming environment that enables code portability among all members of the VPXxFS family. The tool suite includes a safety-certified optimizing C/C++ vector compiler, debugger, instruction set simulator, as well as vector-based DSP, machine learning inference and linear algebra libraries.
